这些与使用Typescript
我有一个从Vue CLi构建的Vue 2项目，它抛出了几十个错误。它可以很好地进行开发，但运行单元测试或为生产构建都会出错。
以下是错误示例，Package.json文件，vue.config.js
以下是一些错误的示例：
这些与使用Typescript?.有关
error in ./tests/unit/store/programme/programme/getters.spec.ts
Module parse failed: Unexpected token (24:38)
File was processed with these loaders:
* ./node_modules/cache-loader/dist/cjs.js
* ./node_modules/babel-loader/lib/index.js
* ./node_modules/ts-loader/index.js
* ./node_modules/eslint-loader/index.js
You may need an additional loader to handle the result of these loaders.

> expect(getters.programme(state)?._id).to.eq(programmeCollection[2]._id);
| });

该问题可能是由使用Javascript可选链接运算符引起的。这是es2020及以上版本支持的功能，显然Vuejs的默认Babel配置不知道如何处理它。
我在Vuejs回购中的一个相关问题中发现了一个建议，以tsconfig.json中的"es2019"为目标，这为我解决了这个问题：
# tsconfig.json
{
"compilerOptions": {
"target": "es2019",
...
}
}
